look up the courant number
Hi everybody!

I'm pretty new in CFD and I've a problem with reversed flow at my pressure outlet. So i looked it up in the online Help.
I just found the conection between reversed flow and Courant Number and Under-relaxation-factor. Where can i look it up? Or does CCM+ compute it for each simulation and each time step for it self?

Thank you very much!

In STAR-CCM+ simulation tree, open the Solverīs node. There you can find the places where you can change the under-ralaxation factors and the size o time-step. The courant number just can be modified if the coupled flow solver was selected.

In star-ccm+ help you can find many information about that.
